Definitions
- the present invention relates to an aircraft control surface configuration, in particular a control surface for aircraft stabilizing surface.
- the supporting surfaces of an aircraft mainly the wings and the stabilizers, comprise control surfaces (flaps, ailerons, slats and spoilers on the wings and steering rudders and elevators on the stabilizers) that are moving parts capable of causing different effects on the course of the flight of said aircraft.
- control surfaces flaps, ailerons, slats and spoilers on the wings and steering rudders and elevators on the stabilizers
- the most common configuration of these control surfaces is that of simple hinge, in such a way that the control surface rotates with respect to the supporting surface on which it is arranged.
- control surfaces for aircraft bearing surfaces called double hinge are known, in which the control surfaces comprise two surfaces, a primary control surface and a secondary control surface, movable with each other and with respect to the surface support of the aircraft.
- one of these designs of double hinge control surfaces comprise two moving surfaces, in which the rotation of the secondary control surface occurs in the opposite direction to the rotation. of the primary control surface, in such a way that the moment of hinge produced by the aerodynamic loads of the aircraft is reduced, thus reducing the force necessary to move the control surface, since the rotation of the primary control surface help to turn the control surface high school.
- the problem posed by such control surfaces is that they do not allow to increase the command power, that is, the aerodynamic force produced by the control surface, in fact they reduce it by reducing the effective curvature.
- Configurations of double hinge control surfaces are also known for aircraft bearing surfaces in which the rotation of the primary and secondary control surfaces is performed in the same direction.
- control surfaces are usually of a total size configuration, the entire control surface of the supporting surface covering the control surface, that is, the secondary control surface covers the entire size of the primary control surface.
- This configuration poses problems of loss of the supporting surface when the angle of attack on it is high, as well as problems derived from the lack of rigidity of the secondary element.
- configurations of control surfaces of double-hinged aircraft in which the rotation of the primary and secondary control surfaces is carried out in the same direction, and which have partial wingspan, the secondary control surface occupying only partially the wingspan of The primary control surface. In these cases, the operation of the primary control surface is carried out through actuators normally located behind the beam of the supporting surface.
- the present invention is oriented to the solution of the inconveniences that have just been raised.
- the present invention develops a double hinge control surface for an aircraft bearing surface, in particular for a stabilizing surface, said control surface comprising a primary control surface and a secondary control surface, occupying the secondary control surface so only partially the wingspan of the primary control surface, the primary control surface being moved, either through a torsion bar integral to said primary control surface, said torsion bar being actuated by one or more actuating elements located within the fuselage of the aircraft, or through actuators located behind the rear beam of the supporting surface, rotating the secondary control surface around a fixed hinge axis with respect to the primary control surface, said surface being in turn of secondary control mechanically connected to Ia bearing surface through one or more connection elements, in such a way that the movement of the secondary control surface is kinematically linked to the movement of the primary control surface, so that the rotation of the secondary control surface occurs in the same sense as that of the primary control surface, thus increasing the command power, that is, the aerodynamic force produced by the control surface as a whole.
- the length of the secondary control surface along its hinge axis is significantly shorter than the length of the primary control surface, the width or chord of said secondary control surface being also significantly narrowed along the direction of its hinge axis and towards the tip of the supporting surface, such that a very advantageous distribution of aerodynamic load on the supporting surface is achieved , thereby achieving greater effective curvature in the inner zone, close to the fuselage, of the control surface and therefore a greater angle of loss of aerodynamic lift due to deflection of the control surface.
- Figure 1 is a schematic front view of the control surface configuration for aircraft bearing surface according to the present invention.
- Figure 2 is a schematic view of the control surface configuration for aircraft bearing surface according to the present invention.
- Figure 3 is a schematic view of the control surface configuration with double flap of total size according to the state of the art.
- Figure 4 is a schematic view of the mechanism of kinematic ligation of control surface with double flap of partial wingspan according to the present invention.
- the present invention relates to a double hinge control surface 1, 10 and 11, for an aircraft bearing surface 2, in particular for a stabilizing surface, comprising ribs 3, rear beam 5 and front beam 4, said control surface 1 comprising a primary control surface 6 which in turn comprises a hinge axis 10, and a secondary control surface 7, which in turn comprises a hinge axis 11, occupying the secondary control surface 7 only partially the wingspan of the primary control surface 6, the primary control surface 6 being moved through a torsion bar 8 integral with said primary control surface 6, said torsion bar 8 being operated by one or more actuator elements 9 located within the fuselage of the aircraft, or alternatively through actuators (not shown) located between the rear beam 5 and the primary control surface 6, the secondary control surface 7 rotating around its fixed hinge axis 11 with respect to the primary control surface 6, said secondary control surface 7 being connected mechanically to the supporting surface 2 through one or more connecting elements 12, such that the movement of the secondary control surface 7 is kinematically linked to the movement of the primary control surface 6, so that the rotation of the Secondary control
- An essential feature of the present invention is that the narrowing of the secondary control surface 7 inside it is such that its chord or local width tends to zero at its outer end 21, with the limitations inherent in the manufacturing process, so that The distribution of curvature between the secondary control surface 7 and the primary control surface 6 along the direction of the wingspan of the control surface
- connection elements 12 are preferably rigid and articulated bars at their ends , by way of connecting rods, which kinematically link the secondary control surface 7 with the supporting surface 2.
- the actuator elements 9 of the torsion bar 8 are preferably servo actuators comprising a lever system.
- the plan form of the control surface 1 that develops the present invention has great narrowing, that is, reduction of the rope or width of the stabilizing and control surface seen in plan view along the length, with respect to the known solutions used at present, contributing this configuration to produce a distribution of aerodynamic load along the wingspan of the control surface 1 of the supporting surface 2 particularly suitable for a control surface 1, for the following reasons:
- the length of the secondary control surface 7 along its hinge axis 11 is significantly shorter than the length of the primary control surface 6 along its hinge axis 10.
- the width or chord of the secondary control surface 7 narrows significantly along the direction of its hinge axis 11 towards the tip of the bearing surface 2.
